Toluene → 1-[2,6-Dichloro-4-(3,3-dichloro-allyloxy)-phenoxy]-3-(4-trifluoromethyl-phenoxy)-propan-2-ol

Participants

Reaction Steps

8 g of 2-(4-trifluoromethyl-phenoxymethyl)-oxirane and 3.8 g of 2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenol are stirred in 80 ml of N-ethyl-diisopropylamine and 50 ml of toluene for 14 days at 100° C. The reaction mixture is concentrated, and the residue is taken up in ethyl acetate and washed with hydrochloric acid and water. After concentration of the organic phase and purification over silica gel, 1-[2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenoxy]-3-(4-trifluoromethyl-phenoxy)-propan-2-ol is obtained. 1H-NMR (CDCl3) 300 MHz: 2.81 (d, 1H), 4.15-4.48 (m, 5H), 4.59 (d, 2H), 6.11 (t, 1H), 6.86 (s, 2H), 7.01 (d, 2H), 7.58 (d, 2H)
